Y Application-med June 12,

To all whom t may concer/L' 1 Be itl known that we, 'HARVEY F. WALTER and GEORGE R. MoNnELY, citizens of the United lStates, residing at Kinston, in the county of'Lenoir, State of North Carolina,

have invented a new and useful Carbonator,

Y ity of devices of that. type to j vention appertains. l

of which'the following is a specification.

This invention aims to 'providenovel floatactuated means whereby the supply of water and gas in' a soda fountain may be controlled.

It is within the province ofthe disclosure to improve generally and to enhance the utilwhich the in- .Vith the above and other objects in view,

which, will appear.` as the description proceeds, the invention resides in the combination and arrangement of parts andin-the.

details of construction hereinafter described and claimed, it beingunderstood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the l spirit of the invention.

Inxthe 'drawings-I Figure 1 shows inelevation, a device constructed in accordance with the invention,

arts being broken away and parts appearlng in section; Figure2 is a transverse sec; tion vtaken approximately on theiline 2- 2 `of Figure 1 and Figure 3 is asectiontakenA approximately on the line 3 -3 of Figure 1.

In carrying out theinvention there is provided a Water receiver 1 A liquid .inlet or source of water vsupply of any desired sort -is provided, the source in. the present instance being Iin the form of a tank-2=connect ed to the'water receiver l-by a pipe`3 wherein a check valve- 4 is interposed,'the' check valve opening toward the water receiverfl.

'Any desired number of mixing chambers are provided,but, for the sake of simplicity, but two mixing chambers 5 and 6 are shown 1n `v the drawings.' A liquid outlet in the form of 4'5 a pipe 7 leads fromv the lower portion ofthe water receiver 1 to the upper' portion of the chamber 5, and in the pipe 7, acheck valve 8 isinterposed, the check valve opening to- -Wardthe mixing chamber 5.- Apipe '9-extends between the top of the mixing chamber conduit;

A seat 27 is fashioned-in the lid 14 at the lower'end of the opening 26.. A casing' 28 is threaded or mounted otherwise on the Vlid'1vl4'of'the water receiver land forms part4 of. a gas conduit.

A downward y (closing valve 43,9 cooperates with the seat 34. The valves '3`8 and 39 are carried by astem 40. The stems 37 and 40 pass through the head 41 'formed A gas supply pipe 35 ,'dischargesinto The lid 14 is .provided with valve 38 cooperates on the outer end of an arm 42. The arm.

40 connectthe'said stem with the head v41 `6 'and v,the chamber 5, the

of the arm .42. Collars 46 on the stem 37 connect the said stem with the head 4.1.

v Anfarm 47 Ais mounted at one end on thev pivot element 43. The'arms 42 and 47 pro- 110 r ject .in opposite directions from the pivot 43. At its outer end, the arn 47 ipe 9 being extended downwardly throug screens or baffles 10` located in thechamber 5. From the mixin chamber 6 extends an outlet pipe 11 provi ed with a faucet 12' of any desired is supplied with a transverse head 48. Retractile springs 49 are connected at 54 with the head 48 of the arm 47.. and are mounted on lugs 50 Aat the ends of the head 41 of the arm/42. The numeral 51 marks a link. The lower end of the link 51 is pivoted at 53 to the intermediate portion of the lever 17.' The upper end of the link 51 lis pivoted at 52 to the arm 47, intermediate ber 5 to elfecta carbonating of the water the check valve 4 holding the water in the tank. When the' faucet 12 is opened thev j When, due to the operation -o the faucet 12, the water-level in the receiver 1 isfl therein. The gas pressure i'n the mixing chamber 5 is not transmitted to the water receiver l, owing to the presence of the check valve 8 in the pipe 7. Water flows from the tank-2 through the pipe 3 into the receiver 1 and air leaves the receiver l through the opening 26, and the pipe 25. When the level of the water rises in the receiver 1, the fioat 23 moves upwardly and, cooperating withthe stop 21 on the 'rod 20 raises'the`rod 20, the lever 17 swinging up- Wardly on its fulcrum 18. When the levcr 17 swings upwardly, the arm 47 is swung upwardly on its fulcrum 43, motion being transmitted to the arm 47 `by the link 5l. When the point of connection between the springs 49 and the lever 47, represented l.-

the part 54, passes above a horizontal plane passing through the pivot element 43, the springs 49 exert on the arm 43, a force which tends to swing the arm 42 upwardly, suddenly. When the arm 42 moves up '..ardly, vthe stems 37 'and 40 are carried upwardly. The valve 36 is moved to a closed position, the valve 39 is moved to an open position, and the valve 38 is moved to a closed position. When the valve 36 is closed, the receiver 1 no longer is vented through the casing 24' and the pipe 25. The pipe 29 is closed bythe action -of the valve 38 and the gas supplied through thevpipe' 35,- passes through theopening133 into the receiver 1,

carbonated vwater in. the connecting chambers 5 andv 6 may be drawn off, since' the liquid infth vreceiver 1 the pipe 7 and When the arms 47 and 42 swing downwardly into the position shown in Figure 1;54V under the action of the sprin s 49, the

downward swinging movement o the arms is limited by a stop 60 mounted on the bracket 16, and extended beneath the arm 47.

What is claimed is e 1. A device for controlling the flow of gas and liquid, embodying a receiver provided adjacent to its lower end with a liquid inlet and with a liquid outlet, the receiver being provided in its upper end with a vent and being supplied at its upper end with a gas conduit communicating with the receiver; means for supplying gas to the conduit intermediate the ends thereof; a valve mechanism which is upwardly movable to close the upper portion of the conduit and to permit a fiow of gas from said means into the receiver, the valve mechanism being downwardly movable to cut ofi' communication between the conduit and the receiver and to open the upper portion of the conduit thereby permitting a flow of nisms embodies a support whereon the float has limited movement; a bracket 'carried by the receiver and having a stop; a radius arm pivoted to the bracketand to thesupport; arms having th'eir inner ends mounted pivotall57 on `the receiver,fthe outenend of one' arm being connected operatively with the valve mechanisms; a retractile springr connecting the arms, the outer ends of the otherarm coacting with the stop under the action of'the spring; and means `for conneeting said other arm with the radius arm.

'In testimony ,that we claim the foregoing as our o wn, we have hereto affixed our signatures. f
